Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchanger technology, and in particular to a phase change enhanced heat transfer system. Background Technology
[0002] Phase change enhanced heat transfer is a technique that enhances heat transfer through changes in the phase state of a substance. In this process, the fluid undergoes a phase transition as it passes through the heat exchanger, such as changing from a liquid to a gaseous state, or vice versa. This phase change is accompanied by the release or absorption of a significant amount of latent heat, and this exchange of latent heat can significantly improve heat transfer efficiency.
[0003] When a fluid exchanges heat through a heat exchanger, it often enters the heat exchanger at a relatively high flow rate. The flow is impeded and its velocity is reduced by the twisted and bent coils inside the heat exchanger, thereby increasing the residence time of the heated fluid in the heat exchanger. However, this operation will eventually cause the fluid to collide with the heat exchanger when it enters the heat exchanger because the fluid still carries a lot of mechanical potential energy. This will cause the heat exchanger to vibrate, and the vibration will be transmitted to the structure on which the heat exchanger is installed, affecting its structural integrity.
[0004] Therefore, a phase change enhanced heat transfer system is proposed to solve or alleviate the above problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a phase change enhanced heat transfer system.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A phase change enhanced heat transfer system includes a support plate, a rigid inlet pipe fixedly connected thereon, and a phase change heat pipe located below the support plate and communicating with the rigid inlet pipe. The phase change heat pipe is connected to the support plate through a flexible connecting pipe, which has elastic deformation properties.
[0008] Preferably, it further includes a connecting base plate, which is disposed below the phase change heat pipe, and when the connecting base plate is fixed, the phase change heat pipe is connected to the connecting base plate by an elastic connector.
[0009] Preferably, a plurality of fins are fixedly connected to the outer side of the phase change heat pipe, and the plurality of fins are evenly spaced in the height direction.
[0010] Preferably, the fins are provided with connecting holes, and a plurality of vertically arranged positive connecting rings are fixedly connected to both sides of the top surface of the connecting base plate, and the two ends of the elastic connector are hooked into the positive connecting rings and the connecting holes, respectively.
[0011] Preferably, vertically arranged connecting side plates are fixedly connected to both ends of the connecting base plate along its length, and horizontally arranged side connecting rings are fixedly connected to the side of the connecting side plates facing each other. The two ends of the elastic connector are also hooked into the connecting hole and the side connecting ring.
[0012] Preferably, the phase change heat pipe is made of copper.
[0013] Preferably, the flexible connecting tube is made of thermoplastic polyurethane.
[0014] This utility model has the following beneficial effects:
[0015] This invention uses a flexible connecting tube to suspend the phase change heat pipe, and then uses an elastic connector to fix the phase change heat pipe. Under normal circumstances, the phase change heat pipe can be confined to the middle position. Once a stream of hot liquid rushes into the phase change heat pipe, the phase change heat pipe will vibrate significantly. This vibration is isolated by the elastic connector and the flexible connecting tube, preventing the vibration of the phase change heat pipe from spreading to the entire equipment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] A phase change enhanced heat transfer system, such as Figure 1 and 3As shown, it includes a support plate 1, a rigid inlet pipe 2 fixedly connected thereto, a phase change heat pipe 8 located below the support plate and communicating with the rigid inlet pipe 2, and a connecting base plate 3.
[0023] like Figure 2 The phase change heat pipe 8 is made of copper. The phase change heat pipe 8 is connected to the phase change heat pipe 8 through the flexible connecting pipe 12. The flexible connecting pipe 12 has elastic deformation properties and is made of thermoplastic polyurethane. Several fins 9 are fixedly connected to the outside of the phase change heat pipe 8. The fins 9 are evenly spaced in the height direction. The fins 9 are also made of copper, and several through holes for the phase change heat pipe 8 to pass through are opened on the fins 9. A connecting sleeve 11 is fixedly connected to the fins 9 and sleeved on the outside of the phase change heat pipe 8.
[0024] The connecting base plate 3 is located below the phase change heat pipe 8. When the connecting base plate 3 is fixed, the phase change heat pipe 8 and the connecting base plate 3 are connected by an elastic connector. The connecting base plate 3 has several through holes 5, which can be used for bolts to pass through and connect to the equipment.
[0025] A connection hole 10 is provided on the fin 9, such as Figure 2 As shown, several vertically arranged positive connecting rings 6 are fixedly connected to both sides of the top surface of the connecting base plate 3. The two ends of the elastic connector are hooked into the positive connecting rings 6 and the connecting holes 10, respectively. Vertically arranged connecting side plates 4 are fixedly connected to both ends of the connecting base plate 3 along its length. Horizontally arranged side connecting rings 7 are fixedly connected to the side of the connecting side plates 4 facing each other. The two ends of the elastic connector are also hooked into the connecting holes 10 and the side connecting rings 7.
[0026] The specific elastic connector is a spring, and hooks are fixedly connected to both ends of the spring, so that both ends can be hooked into the connecting hole 10, the positive connecting ring 6, and the side connecting ring 7.
[0027] When the entire phase change enhanced heat transfer system needs to be installed, simply install the connecting base plate 3 on the inner bottom surface of the installation space, and connect the bolts to the equipment by passing them through the through hole 5, thereby fixing the connecting base plate 3 and the connecting side plate 4. Then, the elastic connector with springs is hooked into the positive connecting ring 6 and the side connecting ring 7 through the pull hook. Next, the phase change heat transfer tube 8 with fins 9 is placed into the space, and the hook at the other end of the spring is hooked into the connecting hole 10. Then, the phase change heat transfer tube 8 is connected to the flexible connecting tube 12, and then connected to the equipment through the support plate 1, sealing the opening of the installation space. During this process, the flexible connecting tube 12 lifts the phase change heat transfer tube 8 and keeps the elastic connector taut.
[0028] In this design, the phase change heat pipe 8 is suspended by a flexible connecting pipe 12 and stabilized by an elastic connector. This arrangement ensures that the phase change heat pipe 8 can be stably maintained in the middle position under normal operating conditions. When hot liquid suddenly flows into the phase change heat pipe 8, it may cause violent vibration of the pipe body. In order to suppress this vibration, the design specifically uses an elastic connector and a flexible connecting pipe 12 to absorb and isolate the vibration, thereby preventing the vibration from being transmitted to the entire equipment and ensuring the overall stability and safety of the equipment.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
